The aim of the paper is to conduct a formative evaluation and assess the implementation of a nursing app using the qualitative TPOM framework to outline how different socio-technical aspects of the process influence digital maturity. The research question is: what are the main socio-technical preconditions for improving digital maturity in a healthcare organization? We conducted 22 interviews and used the TPOM framework for analyzing the empirical data. Exploiting the potential of lightweight technology demands a mature healthcare organization motivated actors’ extensive collaboration, and good coordination of the complex ICT infrastructures. The TPOM categories are used to show the digital maturity of the nursing app implementation in relation to technology, human factors, organization, and the wider macro environment.
